@chrisgtl I went through a similar demo journey about 9 months ago, including many of the speakers on your list, plus various amps and digital sources.
My only advice would be to break this into a number of different sessions as otherwise there is too much to take in and mental fatigue will set in. Also worth taking a friend or partner along if you’ve got a willing participant as it’s helpful to have someone else to talk through what you’re both hearing. Can help with overcoming some of the confirmation bias that can otherwise creep in.
Enjoy - it’s a lot fun
